电液负载模拟器同步结构解耦研究
Research on Synchronous Structure Decoupling of Electro-hydraulic Load Simulators
摘要
Abstract
In order to study the extra torque problems of EHLSs,taking the valve control swing motor of EHLS as an object,a new principle of synchronous structure coupling was proposed,which was based on the analyses of the extra torque mechanism and influence factors.The concrete way was to design the load actuator into a compound bilayer structure,where the outer synchronous motor was used to track the bearing motor for position synchronization control,and the inner motor was used to load.Through the load actuator of the compound structure,the passive loads were modified into active loads,and the problems of extra torque were solved fundamentally.The principles of parameter matching,the design of the seals and the structures of the compound swing motors were given,and the rationality of the oil duct in the inner and outer motors was simulated and tested.Finally,through simulation analysis of EHLS under small gradient loading,the correctness and effectiveness of synchronous structure decoupling were verified.关键词
